and a signal line 103 passing through the second opening 101b and connected to the connection terminal 102b for transmitting the wireless signal output by the feed connector 102.

The antenna connection module is applied to a mobile communication scene of the terminal equipment, and the terminal equipment with the antenna connection module can be connected with an antenna radiator and a mainboard in the terminal equipment through the antenna connection module, so that the antenna can receive and transmit wireless signals to establish communication with a base station. Wherein, the mainboard is provided with a processing module; the antenna radiator can receive and transmit wireless signals of various frequency bands, for example, the antenna radiator can receive and transmit wireless signals of B1, B3 and B39 frequency bands, and can also receive and transmit wireless signals of Wi-Fi2.4GHz or 5GHz frequency bands.

The antenna connection module is provided with a cavity, and the cavity is provided with an accommodating space which can be used for accommodating the feed joint and the signal wire. In some embodiments, the feed joint may be fixed relative to the cavity, enabling a contact connection between the feed end of the feed joint and the antenna radiator; in other embodiments, the feed connector is also movable relative to the cavity, so as to achieve a resilient connection between the feed end of the feed connector and the antenna radiator.

The first chamber wall of the chamber has a first opening. The first opening is used for exposing the feeding end of the feeding connector. Before the antenna connecting module is assembled on the antenna radiator and the mainboard, the exposed feed end is suspended; when the antenna connection module is assembled between the antenna radiator and the mainboard, the exposed feed end is abutted against the antenna radiator and used for outputting a wireless signal to the antenna radiator or receiving the wireless signal output by the antenna radiator.

In the embodiment of the disclosure, the first opening needs to be matched with the feeding end, so that the feeding end can be better exposed at the first opening. The first opening is matched with the feeding end, and may include that the shape of the first opening is matched with the shape of the feeding end, for example, the shape of the first opening and the shape of the feeding end may be set to be the same or similar; it may also be included that the size of the first opening matches the size of the feeding end, e.g. the size of the first opening may be arranged to be larger than or equal to the size of the feeding end.

One part of the signal wire is positioned in the cavity and is connected with the connecting end; the other part of the signal wire is exposed outside the cavity and can be connected with the mainboard, and then the wireless signal output by the feed connector can be transmitted to the mainboard through the signal wire, so that the receiving and transmitting functions of the antenna are realized.

For example, the connection mode of the connection end of the feed connector and the connection of the signal line includes welding or bonding through a conductive adhesive, and the embodiment of the disclosure is not limited.

In the embodiment of the present disclosure, an antenna radiator is taken as an example of a Wi-Fi antenna, and fig. 3 is a simulation diagram of the Wi-Fi antenna.

The return loss of the Wi-Fi antenna at the frequencies of 2.4G and 5.37G can meet the antenna requirement through verification.

FIG. 5 is a graph illustrating the total radiation efficiency of the Wi-Fi antenna for radiating wireless signals, as shown in FIG. 5, the total radiation efficiency is-9.1825 dB when the Wi-Fi antenna radiates wireless signals at 2.392G frequency; the total radiation efficiency when the Wi-Fi antenna radiates a wireless signal at a frequency of 5.364G is-2.2033 dB. The total radiation efficiency of the Wi-Fi antenna at 2.392G and 5.364G frequencies can meet the antenna requirements through verification.

Compared with the prior art that the antenna radiator is connected to the adapter plate through the elastic sheet and then connected with the mainboard through the signal line, the embodiment of the disclosure does not need to arrange the adapter plate and respectively arrange the elastic sheets for connecting the adapter plate and the antenna radiator, and only needs one antenna connecting module to complete the connection, so that on one hand, the connection structure of the antenna radiator and the mainboard can be simplified, the antenna assembling steps can be reduced, and the antenna assembling efficiency can be improved; on the other hand, an antenna connection module occupies the space of the terminal device, which is obviously smaller than the space of the terminal device occupied by the spring plate and the adapter plate required by the existing antenna connection, so that the space occupied by the terminal device can be saved, and the space utilization rate of the terminal device is improved.

For example, the feeding connector can move outwards the cavity through the first opening based on the elastic piece; the feed connection can also be caused to move into the cavity through the first opening.

In the embodiment of the disclosure, the size of the connection end of the feed connector can be set to be larger than that of the first opening, so that when the feed connector moves at the first opening, the connection end can be better positioned between the first cavity wall and the second cavity wall in the cavity, and the situation that the feed connector moves out of the first opening due to the action of the elastic piece can be reduced.
